2 Drowning Terminology Drowning 2

3 Drowning Outcomes Death Morbidity No Morbidity Drowning Process Begins to voluntarily hold breath Continuum of events begins Gas exchange interrupted Will most likely breathe in liquid Drowning Outcomes 3

4 Cough Reflex Drowning is respiratory impairment from submersion Objectives 1. Discuss submersion injury statistics 2. Explain causes of submersion injuries 3. Understand submersion injury patterns 4. Explore rescue and extrication considerations for submersion injury patients 5. Describe assessment and treatment of a submersion injury patient Objective 1: Submersion Injury Statistics 4

5 Submersion Injury Statistics 6,500 deaths per year Children 2 nd leading cause of injury related death < 1 year old bathtub, bucket, or toilet Bimodal death distribution Lack of supervision Lack of skill Risk-taking behavior and intoxication Submersion Injury Statistics While many children survive with little adverse effect, permanent damage can result Submersion Injury Statistics Large disparities exist in occurrence of drowning 5

6 Seasonal Distribution Geographic Distribution 90% of drownings occur in freshwater > 50% are in home swimming pools Submersion Fatalities and Alcohol Alcohol intoxication is involved in 25-50% of adolescent and adult water Click to Continue recreation fatalities 6

7 Objective 2: Submersion Injury Causes Drowning Pathophysiology Submersion Exhaustion Poor swimming skills Seizure Intoxication Trauma Drowning Pathophysiology Submersion Attempt to Breathe Laryngospasm 7

8 Drowning Pathophysiology Submersion Attempt to Breathe Influx of water collapses alveoli Reduces surface for gas exchange Aspiration Drowning Pathophysiology Submersion Dry Attempt to Breathe Wet Suffocation Hypoxia Brain Damage Drowning Pathophysiology Submersion Attempt to Breathe Laryngospasm Aspiration Suffocation Hypoxia Brain Damage 8

9 Drowning Pathophysiology Water flows to the lowest spot No action is required to remove inhaled or ingested water Cause of Submersion Trauma Seizures Cardiac disease Hypoglycemia Syncope Exhaustion Intoxication Hypothermia Length of Submersion U.S. COAST GUARD SLIDE < 1 hour begin resuscitation > 1 hour body recovery 9

10 Cold Water Drowning Water temp < 70 o F (21 o C) Fresh Water vs. Salt Water Both cause alveolar damages and disrupt gas exchange Treatment is the same U.S. COAST GUARD DIGITAL Water Purity 10

11 Time to Treatment Immediate BLS from bystanders is better than delaying treatment until EMS arrives Patient Age Generally, young healthy kids, submerged for a short duration, in very cold water that receive immediate BLS treatment after extrication have a better chance of survival Click to Continue Objective 3: Submersion Injury Patterns U.S. COAST GUARD DIGITAL 11

12 Identify and Treat Life Threats On-scene BLS that leads to a spontaneous return of pulse has the greatest impact on patient survival U.S. COAST GUARD DIGITAL Spinal Cord Injuries Cervical spine or head injuries, if present, are typically the cause of submersion Respiratory Complications Unsuccessful Resuscitation Pulmonary Edema Pneumonia 12

13 Hypothermia Focus treatment on the cardiopulmonary arrest Altered Mental Status Rocco Altobelli Collection Hypoglycemia Hypothermia Hypoxia Traumatic brain injury Seizure Intoxication Click to Continue Objective 4: Rescue and Extrication Considerations 13

14 Rescue and Extrication Keep patient s head above water Move patient along their vertical axis Float a backboard under the patient Reach! U.S. COAST GUARD DIGITAL Victim: awake and active Offer a reach or throw assist Throw! Aim for just beyond and upstream Let current wash the rope into the patient A strong rescue team may be needed Rocco Altobelli Collection 14

15 Go! If patient is silent, still, or not able to keep their head above water, they can not assist in their own rescue Swimming Rescue U.S. COAST GUARD DIGITAL Submerged Patient Clear water and known depth enter water feet first and swim patient to surface Begin spinal immobilization in the water Conditions of unknown depth, poor visibility, current, or hazardous bottom conditions consider probing for patient Prolonged search becomes a body recovery Click to Continue 15

16 Objective 5: Assessment and Treatment 1.5. Describe assessment and treatment of a submersion injury patient US Coast Guard Digital Scene Size-up Team Safety Use incident command system Appoint a safety officer Consider a rehab station Mixed MOI Trauma Medical Environment 16

17 MOI/NOI Cause of submersion MOI for spinal cord injury Patient s AVPU at time of extrication How patient was rescued Bystander treatments applied before your arrival Any changes in the patient s condition Spinal Immobilization Mechanism of Injury Positive Uncertain Negative Manage spine stable with full body immobilization Spine immobilization not needed Additional Resources U.S. COAST GUARD SLIDE Is there a swiftwater rescue team in your area? Does your service have a rescue boat and water rescue equipment? When was the last time you practiced using water rescue equipment? 17

18 Initial Assessment In the water Open airway Rescue breathing U.S. COAST GUARD SLIDE Chest compressions Only effective when patient is on a hard surface Airway Management Normal Methods Suction Positioning Finger sweep Abdominal thrusts are only indicated if patient has an airway obstruction. They are ineffective at removing aspirated water and waste valuable resuscitation time. Airway Management Expect the patient to vomit Remove with: Finger sweep Suction Recovery position U.S. COAST GUARD SLIDE 18

19 Breathing Check Breathing Check Pulse No breathing, pulse present Maintain open airway BVM ventilation with high flow O 2 Circulation Check Breathing Check Pulse No breathing, no pulse No breathing, Pulse present Maintain open airway CPR with BVM ventilation with high flow O 2 Maintain open airway BVM ventilation with high flow O 2 Spontaneous Breathing Present Check Breathing Check Pulse No breathing, No breathing, Breathing and No pulse Pulse present pulse present Maintain open airway CPR with BVM ventilation with high flow O 2 Maintain open airway BVM ventilation with high flow O 2 Maintain open airway high flow O 2 by BVM or nonrebreather 19

20 Wet Clothing Removal Prevent additional heat loss A wet patient will loose heat quickly through evaporation, radiation, convection, and conduction If no pulse Apply AED ASAP Follow prompts to deliver shocks, reassess patient, and resume CPR Treatment: BLS Transport Priority Any submersion injury patient with any ABC problems is a high priority patient U.S. COAST GUARD DIGITAL 20

21 Focused History and Physical Exam Complete as time allows Reassess for breath sounds U.S. COAST GUARD DIGITAL SAMPLE Frame by frame movie of what happened before, during, and after submersion U.S. COAST GUARD DIGITAL Reassess Vital Signs Three One sets Two sets starts starts merely interesting a to trend tell a story 21

22 ED Evaluation U.S. COAST GUARD DIGITAL Survival Prognosis Good if awake upon hospital arrival Poor if CPR still in progress 35-60% of patients die % of survivors have long term neurological side effects Suspected Child Abuse During your scene size-up and history questions to the parent, be aware of clues of child abuse 22

23 Injury Prevention Ideas Controlling access to swimming pools Adequate adult supervision anytime children are in or near the water, including a bathtub or buckets of water Encouraging use of US Coast Guard approved personal flotation devices Discouraging i alcohol l and drug use during recreational water activities like swimming and boating Check the water depth before diving Offer community CPR and first aid course for new parents and babysitters Swimming lessons Lifeguard supervision at pools and beaches Summary: Drowning/ Near Drowning Standard BLS and ALS interventions are indicated for submersion injuries, regardless of the mechanism Begin rescue breathing and high flow supplemental oxygen as soon as possible The prognosis is better if there is an early return of spontaneous circulation If a submersion injury patient is resuscitated, before or after EMS arrival, a hospital evaluation is still indicated Every submersion injury is preventable Rescuer safety is number one do not become a second victim Other Environmental Emergency CE Courses Hypothermia: Assessment and Treatment Heat Emergencies Lightning Injury Prevention and Treatment Avalanche: Rescue, Injury, and Treatment US COAST GUARD DIGITAL 23
